Which statement best describes rapid prototyping?

• A. Is only cosmetic prototypes
• B. Allows designers to generate parts quickly, directly from 3D models, for mockup and testing
• C. Requires expensive tooling
• D. Is used to replace manual drafting entirely

Answer: (B)

Rapid prototyping is about quickly turning a digital design into a physical part so you can test and refine it early. The key benefit is that you can generate parts directly from a 3D model, allowing fast creation for mockups and real-world testing of fit, form, and function. This enables rapid iteration and learning without waiting for expensive tooling or production setup.

That’s why the statement is the best fit: it directly describes producing parts from 3D models for quick mockups and testing, which is the core purpose of rapid prototyping. It isn’t limited to cosmetic models, doesn’t require costly tooling, and it doesn’t replace manual drafting entirely—drafting and documentation still play their roles alongside rapid prototyping.
